CMS Data Analysis: Current Status and Future Strategy
We present the current status of CMS data analysis architecture and describe
work on future Grid-based distributed analysis prototypes. CMS has two main
software frameworks related to data analysis: COBRA, the main framework, and
IGUANA, the interactive visualisation framework. Software using these
frameworks is used today in the world-wide production and analysis of CMS data.
We describe their overall design and present examples of their current use with
emphasis on interactive analysis. CMS is currently developing remote analysis
prototypes, including one based on Clarens, a Grid-enabled client-server tool.
Use of the prototypes by CMS physicists will guide us in forming a
Grid-enriched analysis strategy. The status of this work is presented, as is an
outline of how we plan to leverage the power of our existing frameworks in the
migration of CMS software to the Grid.Comment: 4 pages, 3 figures, contribution to CHEP`03 conferenc
Semi-automated creation of converged iTV services: From macromedia director simulations to services ready for broadcast
While sound and video may capture viewersâ attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution
is this new type of interactive content, offered
in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop
multimedia authoring package Macromedia Director
into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals.
The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper.
In the following sections, an overview of the
operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services.
The next section examines a number of metadata
languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services
User kansei modeling and eco-design
The use of day-to-day life artifacts is a key phase in the lifecycle of products. Indeed it has a great impact on our environment. User centered methods are not yet taken into account in eco-design approaches. These methods are being developed in two ways, by building new user models encompassing complex dimensions such as Kansei and experience, including values and moods, and by integrating the user himself in the design process. This paper deals with setting-up a new theoretical framework associating user-centered design advanced approaches such as experience design, Kansei studies, or participative design and eco-design methods. The final goal is to support product design by providing some guidelines according to environmental issues linked to the users and their abilities
Report of the user requirements and web based access for eResearch workshops
The User Requirements and Web Based Access for eResearch Workshop, organized jointly by NeSC and NCeSS, was held on 19 May 2006. The aim was to identify lessons learned from e-Science projects that would contribute to our capacity to make Grid infrastructures and tools usable and accessible for diverse user communities. Its focus was on providing an opportunity for a pragmatic discussion between e-Science end users
and tool builders in order to understand usability challenges, technological options, community-specific content and needs, and methodologies for design and development. We invited members of six UK e-Science projects and one US project, trying as far as
possible to pair a user and developer from each project in order to discuss their contrasting perspectives and experiences. Three breakout group sessions covered the
topics of user-developer relations, commodification, and functionality. There was also extensive post-meeting discussion, summarized here.
Additional information on the workshop, including the agenda, participant list, and talk slides, can be found online at http://www.nesc.ac.uk/esi/events/685/

The Transitivity of Trust Problem in the Interaction of Android Applications
Mobile phones have developed into complex platforms with large numbers of
installed applications and a wide range of sensitive data. Application security
policies limit the permissions of each installed application. As applications
may interact, restricting single applications may create a false sense of
security for the end users while data may still leave the mobile phone through
other applications. Instead, the information flow needs to be policed for the
composite system of applications in a transparent and usable manner. In this
paper, we propose to employ static analysis based on the software architecture
and focused data flow analysis to scalably detect information flows between
components. Specifically, we aim to reveal transitivity of trust problems in
multi-component mobile platforms. We demonstrate the feasibility of our
approach with Android applications, although the generalization of the analysis
to similar composition-based architectures, such as Service-oriented
Architecture, can also be explored in the future

Towards an Accessible Personal Health Record
Patient empowerment frameworks, including personal health records (PHR), actively engage technology empowered citizens in their healthcare. Particularly today, with the current increase of chronic diseases, the high growth rate of the elderly and disabled populations and at the same time the much higher cross-border patient mobility,such systems may prove to be lifesaving, cost effective and time saving. Currently, there are many different online applications promoted as being functional, user-friendly and detailed enough to provide a complete and accurate summary of an individualâs medical history. However, it seems that most of the Web services available do not fully adhere to well known accessibility standards, such as those promoted by the W3C, thus turning them away from people with disability and elderly people, who most probably need them most. Additionally, support for mobile devices introduces additional obstacles to users with disability when trying to operate such services. This paper presents fundamental (design for all) guidelines for the successful implementation of an accessible ePHR service that can be operated by any patient including people with disabilities irrespective of the device they use to access this service
